metgrab: Image Processing on video streams

I got a toy, a video capture card called a Matrox Meteor. In 1996, this
was a totally bitchin' video capture card! I was starting to mess around with
it programatically and the only reasonable UNIX driver for it was in FreeBSD.
The existing softare that it worked with was mostly for video confernecing.
Pretty boring over the slow links everyone seemed to have back then. So at
first, I just decided to get familiar with the driver API and write a simple
app to display the images into an X11 window. As I got that working, I decided
to screw around with image processing and just overall neat effects on the live
video feed.

All these pics were grabbed with different versions of my grabber, with
different effects, some were planned, others are bugs. Now, its pretty easy to
see these effects on other still pictures, but doing them realtime on video is
amazing. The edge detection pictures looks decent, and you can pull off
the same stuff Photoshop, but when you walk around the your house with the
video camera and then play it back through the edge detection filter, the world
turns into a giant animated sketch.. its one fo the neatest things I've ever
seen animated. Skin tones and wrinkles come to life, even though everything
looks sketched.
